Risk factor control after ischemic stroke or transient ischemic attack

Abstract

Objective

We aimed to estimate the status of risk factor control after ischemic stroke or transient ischemic attack (IS/TIA), and the influence on recurrent stroke in rural communities of northeastern China.

Methods

This population‐based, prospective cohort study enrolled adults aged ≥35 years residing in rural northeastern China. We conducted cardiovascular health examinations in 2012–2015 and followed up in 2018 to record any cardiovascular event. Control of risk factors after IS/TIA was determined through a baseline survey. The Cox proportional hazard model was used to evaluate the relationship between uncontrolled risk factors and stroke recurrence.

Results

Of the 10,700 participants, 575 were diagnosed with IS/TIA and were included in the analysis. At baseline, the rates of control of risk factors were as follows: fasting plasma glucose (FPG), 81.6%; not currently smoking, 65.7%; and achieving physical activity targets, 61%. Blood pressure (BP), low‐density lipoprotein cholesterol (LDL‐C), and body mass index (BMI) were poorly controlled (28.3%, 26.3%, and 37.4%, respectively). The rate of stroke recurrence was 12% during a median follow‐up of 4.43 years. After adjusting for age, sex, ethnicity, family history of stroke, and current drinking, uncontrolled BP and not achieving physical exercise targets were associated with an increased risk of recurrence (hazard ratios: 2.081, 1.685, respectively; p < .05). Uncontrolled FPG, BMI, or LDL‐C and current smoking did not significantly influence recurrent risk (p > .05).

Conclusions

Control of risk factors after IS/TIA needs to be improved in rural communities of northeastern China to prevent recurrence and thus alleviate the public health and economic burden of stroke.
